Naim NAC 552 Network Player

The NAC 552 features a distinct two‑box setup—a separate power supply and preamp—to vastly reduce electromagnetic interference. The 800 VA toroidal transformer, trio of smoothing capacitors, and new discrete regulator provide ultra-clean, rock‑solid power 

A New Standard in Reference Preamplifiers

Since its introduction in 2002, the NAC 552 has been regarded as Naim’s flagship second only to the NAC S1. Built without compromise, it continues a lineage that began with the revolutionary NAC 12

Chassis Suspense: Harnessing Vibration Control

Core audio circuitry resides on a brass sub‑chassis that is fully suspended by low‑frequency coil springs. This mechanically isolates sensitive electronics from external vibrations, preserving signal purity 

Precision, Power & Flexibility

Connect any source via seven DIN and two RCA analogue inputs, with two configurable for unity gain (perfect for phono stages). Six front-panel source selectors, plus independent listen and record banks, provide effortless control. AV-bypass mode simplifies integration with home‑theatre systems 

Key Features
  • Two‑box design: preamp and separate 552 PS power unit isolating EMI
  • Split‑rail power supply: 800 VA toroidal transformer with discrete regulator for ultra-low noise
  • Suspended brass sub‑chassis: vibration damping for pristine signal integrity
